VSYRINGE SPECIFICATION forming part of Letters Patent No. 407,934, dated July 30, 1889. Application led February 26, 1589. Serial No. 301,181. (No model.)

T0 all whom, it may concern:

Be it known that l, JAY W. KrRKwooD, of Silver Mountain,in the county of Boise, Idaho Territory, have invented a new and useful Improvement in Syringes, of which the following is a full, clear, and exact description.

This invention relates t`o syringes for the treatment of female diseases and it consists in certain novel constructions and combinations of parts, substantially as hereinafter described, and pointed out in the claims, the whole forming an instrument which can readily be used by the patients themselves, and by which the following objects are attained: First, it will dispense with the use of forceps, speculum, and absorbent cotton, new commonly used in thc treatment of female diseases for the purpose of removing fetid matter, thus doing away with the irritation, pain, and disgust attendant thereon; second, it will insure absolute cleanliness; third, it will save the physician much annoyance; fourth, it will save expense to the patient, who is enabled to use it without the assistance of a physician, and will therefore be less harassing to a patients feelings; fifth, it leaves the tissues of the parts being treated in the most favorable condition for the application of such remedies as the disease may require; sixth,it serves as a means to apply the necessary medicaments.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar letters of reference indicate 'corresponding parts in all the figures.

Figure l represents a mainly sectional lougitudinal view of my improved syringe, and Figs. 2 and 3 longitudinal sections, upon a larger scale, of the rear and forward portions of the syringe, omitting the piston and its operating-rod. Fig. 4 is a transverse section upon the line ac .r in Fig. 2, and Fig. 5 is a front end view.

Various materials may be used in the manufacture of thc syringe, but generally it will be principally made of hard india-rubber or German silver. p

The construction of the syringe is substantially as follows: A indicates an outer case or cylinder, which has screwed onto its forward end, as at l), an inclined-faced nozzle B, provided with a cup-shaped cavity c in front and having an outer rounded and beveled front edge d, central suction-aperture c in its back, and a series of contracted ducts f within its outer walls arranged to diverge from an inner shouldered end part g, through which said ducts open, to and through the outer beveled surface of the rounded or beveled front edge or rim (l of the nozzle.

O is an inner tube or cylinder arranged concentrically within the outer cylinder A, so as to leave a narrow space 7l between them, and extending from within the front shouldered end part g of the nozzle to the back end of the cylinder A, where it is provided with a thickened shouldered portion i', having inner and outer screw-threads adapted to receive on or over it the rear end of the cylinder A, and within it a screw cap or head D. The inclined ducts f, at the forward end of the syringe, connect with the channel or space h between the tubes A and C, and the interior of the tube O is in connection in its rear with the channel or space h by a series of perforations 7c.

E is t-he piston of the syringe, h Y:ing av leather or other suitable packing Z, and an attached operating-rod F, which passes out through a hole in the cap D, and is provided at its back or outer end with .a ring or any other suitable hand-le. The inner face of the cap D has an enlarged central recess m, preferably of dovetail shape, within which is sprung or fitted a soft-rubber washer or packing n., inclosing the rod F, to prevent the escape of fluid past said rod f rom the interior ate avacuum in the tube C back of uthe piston and cause the water to be drawn through the ducts f, along the channel h, and through IOO the perforations 7c into the tube C. Such charging action, it will be observed, is directly opposite to that of ordinary syringes, and so is the expelling action of the syringe, as will be hereinafter described-hat is, the motion of the piston is a reverse one in both instances', as compared with ordinary syringes; or, especially when applying medicated iiuids, the syringe may be charged through the opening r in the cap upon removing the stopper s, thev piston then being adjusted forward.

The charged syringe is inserted into the patient so that the neck of the uterus will lie in or near the perforated cup portion c of the nozzle B, and on drawing back the piston it will cause'the neck of the uterus to be drawn into said cup portion c, and the foreign matter will seek through the aperture e the vacuum in the tube C, in front of the piston, thus created by the motion of the latter, while the water or medicated fluid in rear of the `piston will be forced out through the perforapurpose. The ducts f, it should be observed, pass outward through the outer beveled surface of the rim d of the nozzle, and so direct the jets of the expelled water or uid away from the cup-shaped cavity in the nozzle.

in combination with a piston fitted to work' within the inner chamber, whereby said syringe operates simultaneously to discharge a diluting or medicated fluid and to remove by suction foreign matter adhering to the mouth or neck of the womb,'als0 the inner chamber of the syringe serves as a vessel to carry off the foreign matter, substantially as specified.

2. In a medical syringe, the cup-shaped nozzle adapted to fit the mouth of the womb and provided with a series of discharge-apertures outside of the suction-cavity in the nozzle, and with' a suction-aperture in the back of the nozzle, whereby a sucking action is combined with a discharging action of water or other fluid in jets, substantially as specified.
